Explanation:
The molarity of the ammonia solution is 1.38 M
<h3>Definition of molarity</h3>
Molarity is defined as the mole of solute per unit litre of the solution. Mathematically, it can be expressed as:
Molarity = mole / Volume
<h3>Determination of the mole of NH₃</h3>
•Mass of NH₃ = 23.5 g
•Molar mass of NH₃ = 14 + (3×1) = 17 g/mol
•Mole of NH₃ =?
Mole = mass / molar mass
Mole of NH₃ = 23.5 / 17
Mole of NH₃ = 1.38 mole
<h3>Determination of the molarity </h3>
•Mole of NH₃ = 1.38 mole
•Volume = 1 L
•Molarity of NH₃ =?
Molarity = mole / Volume
Molarity of NH₃ = 1.38 / 1
Molarity of NH₃ = 1.38 M
